CTE in SQL | Common Table Expression | SQL WITH Clause | CTE Query Performance | Advanced SQL
In this video you will learn about CTE (Common table expressions) In SQL. The WITH clause really simplifies the complicated queries, and makes the SQL queries readable.
with Inner query we can see the code getting messy and there is a lot of redundancy.
Also we have talked about the performance of queries using CTE.
We even saw how CTE can degrade the performance.
CTE is very important from SQL Interview perspective, I hope this video should have given you a good idea on how to work with Common table expression in SQL.
